swift return array from another array with contain string

问题

if we have an array that contain strings for example {"houssam","hassan","taleb"}

and we have a string = "ss"

I need to return an array that return the string which contain ss, so in this case we have {"houssam","hassan"}

What is the best method to do that?

Thanks,

You can try this:

let string = "ss"
let array = ["houssam","hassan","taleb"]
let filtered = array.filter() { $0.containsString(string) }

回答2:

let filterUsers:[String] = []
let users = [String] = ["houssam","hassan","taleb"]
let searchString = "ss"
filteredUsers = users.filter({( user: String) -> Bool in
    let stringMatch = user.rangeOfString(searchString)
    return stringMatch != nil
})

We filter the array of users and check to see if and where it contains "ss". It adds everything to the array where it found "ss" at least once.
